in_array Modifier

Check if an array contains a specific value. Returns true if a match is found.

The first parameter is the "needle" to find in the "haystack". It will read from the context if there is a matching variable, otherwise it will use the parameter as the value. You can pass multiple arguments.

shopping_list:
  - eggs
  - flour
  - beef jerky
want: eggs

{{ if (shopping_list | in_array('flour')) }} GOT IT! {{ /if }}
{{ if (shopping_list | in_array('want')) }} GOT EM! {{ /if }}
{{ if (shopping_list | in_array('eggs', 'flour')) }} YES I DID NOT FORGET! {{ /if }}

GOT IT!
GOT EM!
YES I DID NOT FORGET!
